Abstract

A processing system may obtain a video chunk of a segment of a video program via a network link, the video chunk encoded at a first bitrate of a plurality of available bitrates for segments of the video program in accordance with a mapping function of buffer occupancy levels to the plurality of available bitrates, determine a bandwidth of the network link based upon the first bitrate, a length of the segment, and an elapsed time to receive the video chunk via the network link, determine that the bandwidth of the network link is between two of the plurality of available bitrates, and increase, responsive to the determining that the bandwidth of the network link is between the two of the plurality of available bitrates, a buffer occupancy threshold of the mapping function for switching to a higher one of the two of the plurality of available bitrates.
